    Answer:

    A.) 0.42 m/s

    B.) 0.53 m/s

    Explanation:

    Given that a horse trots rightward 15m to eat a carrot then walks 20m to eat another. Then turns leftward to walk 4m the horse walks a total time of 74s

    A.) what is the horses average velocity to reach the apple?

    The average velocity of the horse will be total displacement divided by total time.

    To calculate total displacement, let the rightward be positive direction and leftward be negative direction.

    Displacement = 15 + 20 – 4

    Displacement = 31 m

    Average velocity = displacement/time

    Substitute all the parameters into the formula

    Average velocity = 31 / 74

    Average velocity = 0.4189 m/s

    Therefore, the average velocity for the horse to reach the apple is 0.42 m/s approximately

    B.) What is the horses average speed to reach the Apple

    Average speed will be total distance covered divided by total time

    Total distance = 15 + 20 + 4

    Total distance = 39

    Average speed = distance/time

    Substitute all the parameters into the formula

    Average speed = 39/74

    Average speed = 0.527 m/s

    Therefore, the average speed for the horse to reach the Apple is 0.53 m/s
